class TGraphBentErrors: public TGraph


TGraphBentErrors class

A TGraphBentErrors is a TGraph with bent, assymetric error bars. The various format options to draw a TGraphBentErrors are explained in TGraphBentErrors::Paint.

The picture below gives an example:

TGraphBentErrors()
 TGraphBentErrors default constructor.
TGraphBentErrors(const TGraphBentErrors &gr)
 TGraphBentErrors copy constructor
TGraphBentErrors(Int_t n)
 TGraphBentErrors normal constructor.

  the arrays are preset to zero
TGraphBentErrors(Int_t n, const Float_t *x, const Float_t *y, const Float_t *exl, const Float_t *exh, const Float_t *eyl, const Float_t *eyh, const Float_t *exld, const Float_t *exhd, const Float_t *eyld, const Float_t *eyhd)
 TGraphBentErrors normal constructor.

 if exl,h or eyl,h are null, the corresponding arrays are preset to zero
TGraphBentErrors(Int_t n, const Double_t *x, const Double_t *y, const Double_t *exl, const Double_t *exh, const Double_t *eyl, const Double_t *eyh, const Double_t *exld, const Double_t *exhd, const Double_t *eyld, const Double_t *eyhd)
 TGraphBentErrors normal constructor.

 if exl,h or eyl,h are null, the corresponding arrays are preset to zero
~TGraphBentErrors()
 TGraphBentErrors default destructor.
void Apply(TF1* f)
 apply a function to all data points
 y = f(x,y)

 Errors are calculated as eyh = f(x,y+eyh)-f(x,y) and
 eyl = f(x,y)-f(x,y-eyl)

 Special treatment has to be applied for the functions where the
 role of "up" and "down" is reversed.
